Britney Spears (search), whose hits include "Oops! ... I Did It Again," has once again tied the knot, the second marriage in nine months for the multiplatinum artist.

Spears, 22, married her fiance, 26-year-old dancer Kevin Federline (search), in a secret weekend ceremony, her record label said Sunday. "She did marry him," Jive Records spokeswoman Sonia Muckle told The Associated Press.

Muckle declined to provide further details. On its Web site, "Entertainment Tonight" said Spears wore a white strapless dress for the wedding, held Saturday evening at a private home in the Studio City area with 20 to 30 people attending.

In January, Spears married childhood friend Jason Alexander (search) in a surprise wedding in Las Vegas. That marriage was annulled 55 hours later.

Spears has gone from posing as a schoolgirl to sing "...Baby, One More Time" and saying sex should be saved for marriage to recording "I'm a Slave 4 U," kissing Madonna during the MTV Video Music Awards and posing nearly nude for magazine covers.

Spears' latest nuptials caught several of her fellow celebrities by surprise.

"Everybody is looking for happiness and love," comedian Ellen DeGeneres said while attending the Emmy Awards in Los Angeles. "She's very young. We got to give her a break."

Spears and Federline announced their engagement in June after dating since early this year.

Federline appeared in the movie "You Got Served" and performed as a backup dancer for singer Justin Timberlake (search), Spears' former boyfriend. He was previously involved with actress Shar Jackson of TV's "Moesha." They have two children — a 2-year-old and a newborn.

At the Emmys, Dennis Haysbert, who plays President Palmer on Fox's "24," joked, "I was just getting used to the other guy."
